to piss off, to get lost, to bugger off, to f*ck off
[verb]
[op-zou-ten. zout-te op, i./h/ op-ge-zou-ten]

"Opzouten" literally translates to "to salt up", hence "to salt(-cure)" or "to pickle". It was used to refer to the activity of salting or pickling fish (herring specifically) in order to store it without going bad. Actually, it was the Dutch who invented the "haringkaken": gibbing…

Nowadays, "opzouten" is mostly used as a vulgar exclamation to tell someone to go away.

Examples:
– "Dit heeft totaal geen nut, opzouten met die onzin!" 
("This is absolutely useless, piss of with that nonsense.")

– "Ik heb goede mensen nodig, praatjesmakers kunnen opzouten." 
("I need good people, boasters can get lost.")

– "Ik ben gekke Henkie niet! Zout maar op met je geouwehoer!!" 
("Do you think I'm stupid or what?! F*ck off with that bullshit!!")

Expressions:
– "Maak dat je wegkomt!": (lit.: make that you get away) get lost! <not vulgar>
– "Scheer je weg!": get lost! <not vulgar, even a bit corny>
